Nectarine plant named ‘R82358’

ABSTRACT

A new and distinct variety of nectarine tree which is distinguished by producing fruit which are mature for harvesting and shipment August 1-5th in the San Joaquin Valley of Central California and where the fruit is high quality, very large, with good flavor and with dark red coloration over the fruit surface.

Latin name: Prunus persica.

Varietal denomination: ‘R82358’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new variety of nectarine tree, Prunus persica var. nectarine, which will be named ‘R82358’ and more specifically as a nectarine tree which produces moderately red and dark red blush color fruit with orange flesh color and very good size which matures for commercial harvest and shipment around August 1-5 in the San Joaquin Valley of Central California. This new variety of nectarine tree has good color, good size and ability to store and ship well. Therefore, this new variety of nectarine should be a commercial success and appealing to the consumer.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The present variety of nectarine was discovered by the inventor. A shipment of seventy nectarine trees was received from a commercial nursery in the Central San Joaquin Valley and planted in Dinuba, Calif. in 2005. One of these trees, a bud sport of ‘Burnectfifteen’ (U.S. Plant Pat. No. 15,622), known as Summer Flare 27, produced the fruit described above. The plant was asexually reproduced by grafting onto ‘Nemaguard’ (unpatented) rootstock in Dinuba, Calif. and reproduces true to type in subsequent generations of asexual reproduction.

SUMMARY OF THE NEW VARIETY

The nectarine tree of the new variety is characterized by producing a fruit for commercial harvest and shipment around August 1-5 in the San Joaquin Valley of Central California.

BRIEF DESCRIPTION OF THE DRAWINGS

The drawing is a colored photograph displaying a leaf shoot with upper leaf surface at the top; to the right is a young twig (branch) and near the bottom of the twig is a stone or pit; just below the leaf shoots are two small fruit, the left one of which displays the stem end, and the right one displays a side view of the fruit; just below that are two additional fruit, the left one of which displays the suture, and the right fruit is cut to display the flesh; to the right is a large fruit displaying the blossom end; and across the bottom of the photo are two leaves displaying lower or bottom sides.

Although the new variety of nectarine tree has the desired characteristics described above that are the result of the growing conditions prevailing near the town of Dinuba in the San Joaquin Valley of Central California, it is to be understood that variation of the usual magnitude may occur due to changes in growing conditions such as irrigation, fertilization, pruning, pesticide, disease control, climatic variations. 

Having thus described and illustrated the new variety of nectarine tree, what is claimed as new and desired to be secured by Plant Letter Patent is:
 1. A new variety of nectarine which is distinguished by producing fruit which is mature for commercial harvesting and shipment around August 1-5th in the San Joaquin Valley of Central California which is characterized by very large fruit with a distinct intense red color over the fruit surface.
